Hawaii is a Zone 4 Corrosion Region

Hawaii is a Zone 4 Corrosion Region


Typically, in tropical areas salt spray (chlorides) from the ocean are carried 35 miles inland. Chlorides are known to accelerate corrosion so we are dealing with chlorides everyday with our island lifestyle. These chlorides form an easy path for condensation to form i.e. in many of our homes and eateries a few grains of rice are mixed with the table salt shaker. The rice absorbs the moisture the salt (chlorides) attracts otherwise, the salt would not come out. Since the corrosion cell works like a battery-operated device which allows the free movement of electrons to pass over the surface of metal, the energy that was used to manufacture the metal in the form of heat, is slowly released back into the environment while consuming the metal in the form of rust and corrosion. 

Those same chlorides also work to accelerate corrosion of metals. 

Various colored oxide deposits form on the solution of chlorides, moisture and oxygen at the active corrosion cell. Heavily scaled oxides on carbon-based steel characteristically look like oversize and thick potato chips that are formed on the good metal substrate.

 The Department of Defense (DoD) has rated Hawaii as a Zone 4 corrosion region - the highest corrosion or most difficult  for metals to survive their design life.  1.None  2.Moderate  3.Severe  4.Extremely Severe 

Combine that with Sulfuric dioxide (VOG from active Volcano on Big Island) + chlorides (Salt from Ocean) = Super Electrolyte resulting in SEVERE CORROSION of all metals.

Did you know in Waipahu, HI our rainfall is 4.5ph = Acid Rain?

Note - Highly corrosive environments, as indicated by the maps, include “severe” and “extremely severe” corrosive regions. A highly corrosive environment does not refer only to areas where the use of road salts or other chemical de-icers is common: high humidity areas, and/or areas with a high concentration of salt in the air are also considered to be highly corrosive.

CarWell CP90/Rust Cop Rust Inhibitor


CarWell CP90/Rust Cop Rust Inhibitor is an excellent product for corrosion protection of welds and dissimilar metals.

Periodic application of CarWell rust inhibitor will control corrosion and extend the life of your fences, equipment and vehicles when applied on a regular maintenance program.

CarWell can be used on new, in-service equipment, parts and even rusted areas and can be applied to more areas than any other conventional rust protection like welds, moving parts, working mechanisms, batteries and leaf springs. CarWell is easy to apply, easy to clean-up and equipment or vehicles can immediately be returned to service. 

How does the product work? Carwell Rust Inhibitor CP90 is a unique, clear liquid blend of rust inhibitors to control corrosion on all metals. It eliminates moisture containing salt, dirt, and air pollutants from the metal surface to give long lasting protection.

Proactive vs Reactive


Living on an Island, nothing escapes the rain and ocean's salt carried by the trade winds. Chlorides also work to form a bridge or a path for the deposits of the spent or consumed metal to travel upon. 

Various colored oxide deposits form with tell tale build up of fine grit or soft to coarse bubbling mounds of these oxide deposits. With concentrations of chloride and moisture being held at the good substrate or below the corrosion oxide deposits, these deposits of rust oxides adds more fuel to the charged corrosion cell as the moisture is held in suspension and works to combine with the chlorides to keep the corrosion cell highly active.  

 Hawaii has many micro climates that exist side by side with strikingly different climatic conditions.  As a result, of the 13 major life zones found in the world, 11 are found in Hawaii. That is the greatest number found in the smallest area in the world which makes corrosion protection a must! Prevention and implementing a maintenance program is KEY to insuring long life for everything you own or manage. Better to maintain what’s good now than try to fix what’s gone wrong later. 

Take anything metal ​(excludes gold and platinum) + combine with Air (Oxygen/Tradewinds) + add water and salt (Sodium Chlorides) + increase temperature to speed up process (Sun) =  Preventable! 

TAKE ACTION NOW to prevent rust or manage rust and corrosion on what you own or manage, because Rust never sleeps - especially in Hawaii!

Stages of Corrosion

Proactive vs Reactive

Proactive vs Reactive


Stages of corrosion are Stage 1 to Stage 4 

Stage 1 - Earliest signs of corrosion. Deposits on the surface of the metal with a red, black or white coloration will form. This will be partnered with a small amount of etching and pitting. At this stage, the rust is attacking the surface of the metal. The rust can be treated easily with either sand blasting or chemically cleaning.

Stage 2 - Corrosion conditions exits on the surface metal. This rust now takes on a powdered or granular condition. Scaling can develop as flakes of metal become loose and fall off. The base metal will still be unaffected at this stage; therefore, the metal can be easily treated with sand blasting or chemical cleaning.

Stage 3 - Corrosion is found with heavy scale, minor edge erosion and more extensive surface damage. Rust, black corrosion accompanied singularly or in – combination with etching, pitting, loose or granular condition. Metal in corroded area is unsound and small pin holes may be present. Corrective action is required

Stage 4 - No metal remains at the point of the most severe corrosion. Looks like Swiss cheese condition, many holes, heavy scale similar to stacked Maui chips and loss of 50% or more of original metal. Corrosion has advanced to the point where the metal has been penetrated throughout. There are holes in the surface area or metal is completely missing along the edges. Replacing the parts or components are generally recommended.
